3 Claims. (01. 24-186) This invention relates to new and useful improvements in slide loops and provides an improved button loop such as is used to'receive a button of a garment tobe supported, such for example as a button of an overall bib to attach thebib to a shoulder strap.

An object of the invention is to provide an improved loop which is easily attached to a button and which is so constructed as to facilitate the attaching operation and prevent casual unhooking or releasing of the button.

Afurther object isto provide a slide loop ineluding. certain improvements in the means for attaching it toa strap and particularly include certain improvements in the slide buckle construction disclosed in my Patent No. 1,892,516 of December 27, 1932.

Other objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, it will be understood that the invention is notlimited to the details 'disclosed but includes all such variations and modifications as fall within thespirit of the invention and the scope of the appended claims. In the drawing: i i Fig. 1 is a front elevational View on'an enlarged 3 scale showing the improvedloop in association with a button and also illustrating a step in mounting of the improved loop on a strap; Fig. 2 is'an edge elevationalview showing the w improved loop in position on a strap and attaching the strap to a button carrying piece which piece may, for example, be a portion of an overall bib;

50 v 'Fig. 8 is a sectional view taken substantially along the line 8-8 of Fig. l, the strap being omitted; and i i i Fig. 9 is a view somewhat similar to Fig. 8 but showingthe slide buckle closed.

55 Referring in detail to the drawing the improved slide loop as here disclosed includes a slide buckle generally designated [0 and comprising certain features disclosed in my Patent No. 1,892,516 referred to above. The buckle ID includes a substantially rectangular frame com- 5 prising longitudinal or side bars H and I2 and end bars l3 and I4, connecting the side bars. Preferably the bars forming the frame are pressed so as to be concavo-convex in cross section whereby to add rigidity to the frame. 10 Formed with one of the end bars or members, as, for example, the endbar I3, is a cross member or central bar I5 extending longitudinally of the frame in the direction of the end bar 14 thereof.

This member I5 is generally U-shaped in trans- 15 are located atthe free. edges of such walls or 20 arms.

Prior to the buckle being applied to a strap or the like the cross member It occupies an inclined position relative to the frame Ill substan-, tially as shown in Figs. 5 and 8 of the drawing. 25 From these figures it will be noted that the cross member inclines outwardly away from the frame whereby there is a space 19 between the free end of the cross member and the adjacent portions of the frame. During the formation of the cross 3 member it is drawn slightly so as to dispose its free end, which comprises a tongue like portion 20, over a lip 2| formed with the end member M of the frame. This lip 2| represents a portion of the frame end bar M which is not pressed upwardly as much as the other sidewhen the frame is treated to render its parts concavo-convex in transverse section, and it .will be noted that the lip is located between raised portions 22 formed when the frame member I2 is pressed to give it rigidity as above eX- plained. Thus the lip Z! is the bottom wall of a recess in the inner edge of the end bar. From the foregoing it will be apparent that the central member or bar l5 may be pressed in the direction of theframe to bring its free end portion 20 into engagement with the lip 2| and that such an operation will locate the tongue like free end portion 2a between the raised portions 22, or in the recess of which lip 2! forms the bottom wall, so that while 5 the free end of the central bar is in engagement with the lip 21 the said end of the bar is held against lateral movement. A lug 23 is carried by the end bar M and when the free end of the cen--' tral bar is pressed into engagement with the lip 25 this lug 23 is bent over against the free end portion of the central bar as clearly shown in Fig. 9 whereby to secure the central bar in position.

The connecting portion 16 of the cross or central bar 5 5 has portions lanced and pressed therefrom to provide teeth or clamping members 24 each connected at one end with said cross member. These teeth are adapted to have an end of a strap inserted beneath them andtheteeth will then be pressed in the direction of the bar l 5 to secure the ends of the strap to the latter.

A strap 25 is indicated in Figs. 1 through 4 and such strap may be a shoulder strap of a pair of overalls, a portion of the bib of which is indicated at 26. However, it will be understood that the invention may be applied to other uses. In applying the buckle to a strap the buckle is slipped onto the strap from the edge thereof by inserting the edge of the strap into the space l9 between the frame and the cross member I5 of the buckle as suggested in Fig. 1. The strap may then be drawn into the buckle or the buckle may be drawn across the strap so as to dispose the edges of the strap inwardly of the free end portion of the cross member.

After the strap is located as described it may be doubled upon itself as clearly shown in Figs. 2, Band 4 and have its free end inserted beneath the teeth 2 Then the entire assembly may be placed in a die and have the cross member 95 pressed in the direction of the frame to dispose the free end 20 of the cross-member between the raised portions 22 and against the lip 2! of the frame after which the lug 23 is bent over against the portion 20 of the connecting member as shown in Fig. 9. During this same operation the teeth 2 on the connecting portion of the cross member are forced in the direction of said member to clamp the end of the strap thereagainst. Of course, the pressing of the teeth 2 against the end of the fabric may take place in an operation entirely separate from that wherein the cross member is pressed against the run of the strap.

With the described construction the buckle may be easily and quickly applied to a strapand the end of the strap secured in an out of the way position. The means for anchoring the free end of the cross memberl after the latter has been pressed against the strap is very simple and economical to manufacture and as the lug 23 holds the end of the connecting member against the lip 2i and below the surface of the raised portions 22 it will be appreciated that the free end of the cross bar or member is securely fastened against any casual movement.

An extension 2'! on the bar l2 provides the improved button loop and such extension is provided with an elongated button entrance slot 2%! and with a button retaining slot 29 communicat ing at its upper or inner end with the intermediate portion of said entrance slot. At the junction of the slots 23 and 29 the material of the extension 27 is ofiset or bent to provide inclined portions 38 which start below the plane of the body of said extension and continue upwardly to provide projections or bumps 3! located one at each side of the rear or inner portion of the slot 29 and extending above the plane of the forward portion of extension 27! or of that portion of said extension in which the button retaining slot 29 terminates.

The loop constructed as described may be easily attached to a button and will not casually become unhooked or released from the button. In the drawing the slide loop has been attached to the strap or the like 25 forming a shoulder strap of an overall, the portion 26 of the bib of Which carries any or the usual button 32. When it is desired to attach the strap 25 to the bib 28 or to button said strap to the bib, the loop is disposed with its inclined portions 33 in advance of an edge of the 5 button 32 and with the lower edges of said portions 30 against the fabric of the bib or at least below the under surface of the edge of the button. Then as the loop is drawn upwardly the inclined portions 323 passing under the button raise its edge 11 as suggested in Fig 3 and as the drawing of the loop continues the button passes through the en trance slot 28 and into the retaining slot 29 of the loop as shown in Figs. 1, 2 and 4.

When the button is in this position it will be 15 noted that the bumps or projections 3| are rearwardly of the center of the button with the portions of extension 21 carrying the retaining slot 29 disposed below the button. Since the bumps or projections tl are rearwardly of the center 20 of the button they serve to prevent casual relative movement of the button and loop in a manner to result in the unhooking or releasing of the button by passage of the latter rearwardly into the entrance slot 28. 25

From this it will be clear that with the improved loop the strap may be easily and quickly buttoned or hooked onto the bib and that the bib will not readily be accidentally unbuttoned or unhooked. The inclined portions 30 greatly 30' facilitate the hooking or buttoning of the strap to the bib since as such portions move under the edge of the button they raise such edge and the button is easily guided into the retaining slot 29. It will be noted that this latter action is 35 assisted by the rounding of the edges 33 at the junction of the slots 28 and 29.

Having thus set forth the nature of my invention, what I claim is:

1. In a device of the character described, 2.40 frame, a cross member integral at one end with the frame and extending across the same, said cross member inclined relative to the frame whereby to dispose the free end of the cross member out of the plane of the frame to permit 45 a strap to be slipped edgewise between the member and frame, said cross member adapted to be pressed in the direction of the frame to engage the strap and bring the free end of the member against a portion of the frame, and a 50 lug on the frame extending transversely of the cross member and bendable over the free end of the cross member into a position against said member to secure the said end of the cross member against said portion of the frame. 55 2. In a device of the character described, a frame, a cross member integral at one end with the frame and extending across the same, said cross member inclined relative to the frame whereby to dispose the free end of the cross member out of the plane of the frame to permit a strap to be slippededgewise between the member and frame, said cross member adapted to be pressed in the direction of the frame to engage the strap and bring the free end of the 5 member against a portion of the frame, said frame including a lip portion against which the free end of'thecross member is pressed and raised portions at each edge of said lip portion and between which said end of the cross member is disposed when in engagement with said lip portion, and a lug on the frame and bendable into position against said end of the cross member to maintain the same against said lip portion.

3. In a device of the character described, a

' frame, a cross member connected at one end to the frame and extending across the same, said member having a tongue like free end portion and being inclined relative to the frame to dispose the said free end out of the plane of the frame to permit a strap to be slipped edgewise between the member and frame, said cross member adapted to be pressed in the direction of the frame to engage the strap and bring the free end portion against the frame, the frame having a recess to receive said tongue and hold it against lateral movement, and a lug on the frame extending transversely of the cross member and bendable over the free end of the tongue into a position over said tongue to retain it in the recess.
